Struct hashbag::Entry

pub struct Entry<'a, T, S>(/* private fields */);

A view into a single entry in the bag, which may either be vacant or occupied. This enum is constructed from the entry method on HashBag

Implementations

impl<'a, T, S> Entry<'a, T, S>

where T: Hash + Eq, S: BuildHasher,

pub fn and_modify<F>(self, f: F) -> Self

where F: FnOnce(&mut usize),

Provides in-place mutable access to an occupied entry before potential inserts into the map.

pub fn value(&self) -> &T

Returns a reference to the entry’s value.

pub fn or_insert(self) -> usize

Ensures there is at least one instance of the value before returning a mutable reference to the value’s count

pub fn or_insert_many(self, quantity: usize) -> usize

Ensures there is at least quantity instances of the value before returning a mutable reference to the value’s count

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
